In order to get the full range out of your servo's, they must be installed in such a way that the entire servo range will map on the entire throw of the Ailerons. This means that you must have equal throw around the center of the servos.

This is the normal situation if you have only one aileron servo, or an Y-cable with two aileron servos in a mirrored setup, or a tail-mixer y-cable with two servos in a parallel setup.

This is shown in the next image, where we used a 'top drive' servo linkage:

If you have a 'normal' servo install, with the control horns on the bottom side of the aileron, the situation is exactly the same. It may only be that you have to inverse the servo direction. That means that -100% will become 100% and vice versa.

We have used the term 'travel' to refer to the % of maximum throw that you want on a certain control surface, such as flaps or ailerons. They are always relative to the max throw.

In order to get the full range out of your servo's, they must be installed in such a way that the entire servo range will map on the entire throw of the Flaps. If you want to use your control surfaces as pure flaps, with only travel down, you must have a 100% offset on the servos to get to the neutral (cruise) position of the flapss. This is the standard situation if you have one servo controlling both flaps, or you use a y-cable with parallel servos, or a tail mixer y-cable with mirrored servos.

This is shown in the next image:

We have used the term 'travel' to refer to the % of maximum throw that you want on a certain control surface, such as flaps or ailerons. They are always relative to the max throw. Flap travel of 100% corresponds to a servo position of -100%. Flap travel of 0% (no flaps) corresponds to a servo position of 100%.

In order to get the full range out of your servo's, they must be installed in such a way that the entire servo range will map on the entire throw of the flaperons. This means that you NEED to have some offset on the servos to get to the neutral (cruise) position of the flaperons.

This is shown in the next image:

This implies that the maximum throw around the Offset for the ailerons is equal to (100-Offset).

This implies that the maximum throw below the Offset for the flaps is equal to (100+Offset).

The JustFly models are all configured to automatically correct the maximum throws based on the above formulas. This means that you will never have to apply differential or adjust for on the rates to compensate for a change in the Offset.

If you have a 'normal' servo install, with the control horns on the bottom side of the aileron, the situation is exactly the same. It may only be that you have to inverse the servo direction. That means that -100% will become 100% and vice versa.

We have used the term 'travel' to refer to the % of maximum throw that you want on a certain control surface, such as flaps or ailerons. They are always relative to the max throw. With flaperons, the max travel for flaps and for ailerons do not influence each other, and can be set fully independantly.
